WILLIAM RITSON WILSON, OF TORONTO, ONTARIO, CANADA.

RAILWAY-RAIL.

To all whom it may concern:

Be it known that I, VILLTAM RrrsoN VIL- sort, a citizen of the UnitedStates of America, resident of the city of Toronto, in the county ofYork, Province of Ontario, in the Dominion of Canada, have inventedcertain new and useful Improvements in Railway- Rails, of which thefollowing is a specification.

The invention relates to improvements in railway rails as described inthe present specification and illustrated in the accompanying drawingsthat form part of the same.

The invention consists essentially in the novel construction andarrangement of parts whereby a separable head is held in place on thepermanent head by a hooked flange on the one side and a straight flangeon the other and is rigidly secured by a plurality of bolts to saidpermanent head.

The objects of the invention are to reduce the cost of maintenance ofways and to devise a rail particularly adaptable for street railwayrails in which a worn head may be easily and quickly removed andreplaced without disturbing the main portion of the rail and thusdisrupting the roadbed and pavements.

In the drawings, Figure 1 is a sectional perspective view of a portionof a rail constructed in accordance with my invention. Fig. 2 is alongitudinal sectional view of a portion of the rail through one of thebolt holes.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the permanent part of the rail havingthe base 2 and a web 3 and a permanent head 4, the sides 5 and 6 of thesaid head 4: being unevenly distributed in relation to said web 3 toobtain a greater width on the side 5.

7 are slots arranged at intervals longitudinally in the side 5 of thehead 4.

8 is the separable head of the rail havinga longitudinal groove 9, inwhich the flange of the car wheel travels, and a downwardly extendinginturned or hooked flange 10 at one side thereof fitting snugly aroundand gripping the outer edge of the side 6 of the head 4, and a straightflange 11 from the other side abutting the outer edge of the side 5. Theflanges 10 and 11 are formed so that the distance between them. isuniform from end to end of the rail and the distance Specification ofLetters Patent.

between them is such that when the inturned flange 10 is hooked over theedge of the head 4., the inner side of the flange 11 will bring the saidflange 10 to grip the permanent head on that side. The head of the railis thus securely held from lateral displacement.

12 are bolt holes through the head 8 in the bed of the groove 9 andarranged at intervals longitudinally therein to register with the slots7 in the head i of the permanentportion of the rail.

13 are bolts extending through the bolt holes 7 and 12 and having theirheads counter sunk in the top of the holes 7 so that the upper surfaceof said heads will be flush with or below the surface of the slot 9.

1a are nuts on the lower end of the bolts 13 and abutting the under sideof the side 5 of the head a and with the said bolts, firmly securing theseparable and permanent heads together.

The longitudinal slots 7 in the side 5 provide for any slight variationin the distances between the bolt holes in the separable head so thatthere will be no difliculty in placing the said separable head inposition besides allowing for the expansion and contraction of themetal.

The peculiar formation of the permanent head 4 is quite important, asthe difference in width of the sides 5 and 6 brings the actual treadportion of the separable head centrally over the web 3 and thus theweight of the car traveling on the rail is supported vertically by thesaid web.

The permanent portion of the rail is made of the ordinary rail steel andis quite flexible and not liable to fracture easily, but the head 7 ispreferably formed of high carbon or manganese steel to resist wear. Acomposite rail is thus formed which will not be liable to break throughcrystallization, caused by vibration, as the weight is supporteddirectly by the low carbon steel portion and an upper running surface ofa hard nature is provided to withstand the wear and tear of the carwheels.

The construction herein described has many advantageous features otherthan those mentioned, the peculiar arrangement of the side flanges ofthe upper portion holding the said upper portion securely from side playand therefore preventing any spreading of the rails and when it isdesired to replace a worn rail it is not necessary to tear up a lot ofthe pavement but merely a few blocks are removed to allow access to thebolts when the same may be loosened and the up per portion of the raillifted clear and a new portion placed thereon without difiiculty. Notonly is the pavement around the rails saved but a saving of much timeand material is effected, as repairs may be made with great celerity.Another important feature in the use of a rail of this description isthat the tread portions may be arranged to break joint with the mainportion so that there is no point in the rails where there is a breakfrom top to bottom. This feature will eliminate a considerable amount ofvibration and noise.

\Vhat I claim as my invention is In a device of the class described, incombination with a base, web and permanent head, said head being formedwith a perfectly fiat upper surface and arranged with a greater width onone side of said web than on the other and having pointed tips formed bythe curved under surface converging to said flat surface andlongitudinal slots head, and a flange extending downwardly from theother edge having a sheer inner edge rounded outwardly at the bottom anda perfectly flat surface between said flanges adapted to rest on theflat surface of said permanent head, and bolts countersunk in saidseparable head and extending through the longitudinal slots in saidpermanent head.

Signed at the city of Toronto, in the county of York, Province ofOntario, in the Dominion of Canada, this eighth day of February, 1908.
